As for steel, the word "metal" can be used as a general term, or more specifically "iron" or "aluminum." Additionally, "reinforcing steel" is often used to describe the type of steel used to strengthen concrete structures. Knowing these synonyms can help you better communicate with architects, builders, and other industry professionals.
